INVESTIGATION OF ULTRA HIGH STRENGTH BULK GLASS

Abstract

A technique is described by which the intrinsic strength of bulk glass can be measured. The technique is applied to examine the factors which influence the engineering strength of glass. Results of tensile strength measurements on bulk borosilicate glasses, obtained by bending tests, approach theoretical values. Measurement of the temperature dependence of strength in the range 350 to 600 C reveals an interesting strength-temperature transformation. Electrical measurements are also performed in this temperature range in an effort to interrelate electrical and mechanical behavior. Sulfide glass preparation and evaluation techniques are described to provide test specimen composites capable of exhibiting intrinsic strength near room temperature.
